CONVERSION MATERIAL, ESPECIALLY FOR A WHITE OR COLORED LIGHT SOURCE COMPRISING A SEMICONDUCTOR LIGHT SOURCE, METHOD FOR PRODUCING THE SAME AND LIGHT SOURCE COMPRISING SAID CONVERSION MATERIAL

摘要

The present invention relates to a kind of transition materials, especially for white or color light source, the white or color light source include semiconductor light source as main light source, the main light source includes host glass, when being used as the block materials that thickness d is about 1mm, the host glass includes in the wave-length coverage of 350~800nm, in the range that main light source shines, internal transmission rate ti is greater than 80%, in the spectral region of 350 nm t, the sum of transmissivity and convergence rate of non-blooming sintering host glass are at least more than 80%. 800 nm of O, in the spectral region of main light source transmitting light. By sintered glass powder (grain size distribution d10 =0.7m, d50 =3m, d90 =150m) and fluorophor, such as cerium-doped yttrium aluminum garnet (YAG, Y3Al5O12) prepares transition material.
